Performance Analysis of LEACH-SCH Protocol for Wireless Sensor Network in Heterogeneous and Homogeneous Region Considering Variable Length of Packet

Abstract: Wireless Sensor Network are networks of large number of small, battery powered sensor nodes having limited on-board storage, processing and radio capabilities .The transmission and reception between source and sink consumes lots of energy as compare to data processing. Designing protocols and applications for such has to be energy aware in order to prolong the lifetime of the network. For this purpose clustering routing protocol is the most common technique used for energy aware routing in WSNs. In this paper, we firstly completely analyzes the basic distributed clustering routing protocol LEACH-SCH (Low Energy Adaptive Clustering Hierarchy- Supporting Cluster Head), then we study the impact of heterogeneity in order to prolong the lifetime of WSN. The simulation results of proposed protocols are compared for its network life time in MATLAB with LEACH protocol.
